Description
Die Erfindung betrifft einen Mehrschichtziegel zur Errichtung eines zweischaligen Mauerwerks nach dem Oberbegriff des Patentanspruchs 1 sowie ein Verfahren zur Herstellung eines solchen Ziegels.The invention relates to a multilayer brick for the construction of a clam shell masonry according to the preamble of
Mit einer umfassenden Veränderung und Weiterentwicklung des Baustoffs Ziegel in den letzten Jahren hat sich immer mehr ein Konflikt zwischen den Anforderungen an die Wärmedämmung einerseits und die Schalldämmung andererseits ergeben, da eine Verringerung des Ziegelrohgewichtes mit verminderten Schallschutzeigenschaften verbunden ist, weshalb sich die Schallschutzeigenschaften mit einer herkömmlichen Optimierungstechnik nicht wesentlich verbessern lassen. Unter einer herkömmlichen Optimierung im Sinne des Standes der Technik wird bei einer gegebenen Abmessung eines Ziegels die Variation des Lochanteils, die Lochgeometrie, die Anzahl der Kammern und die Füllung der Hohlräume mit schalldämmendem Material verstanden. Es ist hierbei evident, dass eine Erhöhung des Lochanteils zur Verbesserung der Schallschutzeigenschaften mit reduzierten Wärmedämmeigenschaften einhergeht und umgekehrt.With a comprehensive change and further development of the building material brick in recent years, more and more a conflict between the requirements for thermal insulation on the one hand and the sound insulation on the other hand result, since a reduction of Ziegelrohgewichtes is associated with reduced sound insulation properties, which is why the sound insulation properties with a conventional Optimization technology can not be significantly improved. Under a conventional optimization in the context of the prior art is understood for a given dimension of a brick, the variation of the hole portion, the hole geometry, the number of chambers and the filling of the cavities with sound-absorbing material. It is evident here that an increase in the hole proportion for improving the soundproofing properties is accompanied by reduced thermal insulation properties and vice versa.
Gegenstand des deutschen Gebrauchsmusters
Aus dem Gebrauchsmuster
Der Erfindung liegt die Aufgabe zugrunde, einen monolitischen Mehrschichtziegel zur Errichtung eines zweischaligen Mauerwerks, insbesondere einer Wohnungstrennwand zur Verfügung zu stellen, der bei mindestens gleichbleibenden oder besseren Wärmedämmwerten wesentlich verbesserte Eigenschaften im Schallschutzbereich aufweist und eine flexible Entkopplung innerhalb des Ziegels zwischen wärmedämmender Tragschale und schalldämmender Vorsatzschale erlaubt.The invention has for its object to provide a monolitic multilayer brick for the construction of a clam shell masonry, in particular a housing partition available that has at least consistent or better thermal insulation significantly improved properties in the noise control area and a flexible decoupling within the brick between the heat-insulating tray and sound-absorbing attachment shell allowed.
Die Lösung dieser Aufgabe ergibt sich aus den Merkmalen des Anspruchs 1. Vorteilhafte Weiterbildungen sind Gegenstand der Unteransprüche.The solution to this problem arises from the features of
Ferner soll ein Verfahren zur Herstellung eines monolithischen Mehrschichtziegels angegeben werden, das gegenüber dem eingangs erläuterten Stand der Technik gemäß
Mit der erfindungsgemäßen Ausgestaltung des aus einem Stück bestehenden Mehrschichtziegels ist eindeutig definiert, welche Aufgaben die Vorsatzschale und die Tragschale übernehmen, die beide über die weichfedernden Verbindungsmittel akustisch voneinander entkoppelt sind. Durch die elastische Entkopplung der beiden Schalen werden wesentlich verbesserte Eigenschaften im Schallschutzbereich erzielt, ohne dass dadurch die Wärmedämmeigenschaften der Tragschale beeinflusst werden.With the inventive design of the one-piece multilayer brick is clearly defined, which tasks take the front shell and the tray, both of which are acoustically decoupled from each other on the soft elastic connecting means. Due to the elastic decoupling of the two shells significantly improved properties are achieved in the soundproofing, without thereby affecting the thermal insulation properties of the support shell.
Da gemäß der Erfindung die beiden Schalen durch das weichfedernde Verbindungsmittel, vorzugsweise weichelastischer PUR-Schaum mit einem dynamischen E-Modul zwischen 0,1 und 6 N/mm2, akustisch voneinander entkoppelt sind, wird der Schalldruck, der auf eine Schale einwirkt, nicht auf die andere Schale übertragen. Als entkoppelndes Verbindungsmittel eignet sich vorwiegend PU-Schaum mit einer Zugfestigkeit zwischen 0,4 und 3 N/mm2, der als Verbindungsschicht flächig zwischen den beiden Schalen aufgebracht sein kann. Alternativ wird allerdings eine Lösung bevorzugt, bei der das Verbindungsmittel in Form von Verbindungselementen punktuell zwischen den beiden Schalen eingesetzt wird, um diese formschlüssig oder kraftschlüssig so miteinander zu verbinden, dass unter Freilassung eines Abstandes eine Entkopplung bewirkt wird.Since, according to the invention, the two shells are acoustically decoupled from each other by the soft resilient connecting means, preferably soft elastic polyurethane foam with a dynamic E-modulus between 0.1 and 6 N / mm 2 , the sound pressure acting on a shell, not transferred to the other shell. As a decoupling bonding agent is predominantly PU foam with a tensile strength between 0.4 and 3 N / mm 2 , which can be applied as a bonding layer area between the two shells. Alternatively, however, a solution is preferred in which the connecting means in the form of connecting elements punctually between the two shells is used to form-fit or non-positively connect with each other so that a release is effected while leaving a distance.
Entsprechend ihrer Funktion in dem „monolithischen“ Mehrschichtziegel, der als fertiger Verbundbaustein vermauert werden kann, ist die biegesteife Tragschale schwerer als die Vorsatzschale, die überwiegend zur Schalldämmung dient. Mit anderen Worten hat die Tragschale eine größere Flächenmasse mF als die Vorsatzschale, wobei gilt:
- pS = Scherbenrohdichte, i. a. zwischen 1,0 und 1,8 kg/dm3,
- dW = Wanddicke
- LA = Lochanteil in Prozent
- p S = apparent density, generally between 1.0 and 1.8 kg / dm 3 ,
- d W = wall thickness
- L A = hole percentage
Um für die Tragschale bzw. die Vorsatzschale die optimale Flächenmasse zu wählen, müssen daher die drei Koeffizienten entsprechend variiert werden, d. h. für die Tragschale eine hohe Scherbenrohdichte von etwa 1,4 kg/dm3, eine große Wanddicke von 14 cm oder mehr und einen Lochanteil von max. 40 %, der geringer ist als bei der Vorsatzschale. Da in der Praxis beide Schalen aus demselben Material hergestellt werden und damit gleiche Scherbenrohdichte haben, müssen die beiden anderen Parameter entsprechend gewählt werden, um die optimalen Werte für die Flächenmasse zu erhalten:
